RUNNING-GEAR FOR DUMPING-WAGONS.

Application filed October 12, 1909.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, LORENZO H. YOUNG, a citizen of the United States, residing at Hagerstown, in the county of Washington and State of Maryland, have invented new and useful Improvements in Running-Gear for Dumping-\Vagons, of which the following is a specification.

This invention relates to running gear for dumping and other wagons, and it has for its object to provide a simple and improved running gear with special reference to the improved construction of the fifth wheel and related parts.

With these and other ends in view which will readily appear as the nature of the invention is better understood the same c0nsists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings: Figure 1 is a side elevation of a dumping wagon constructed in accordance with the invention. Fig. 2 is a bottom plan view of the forward portion of the box supporting frame, showing also a portion of the wagon box. Fig. 3 is a top plan View of the front portion of the running gear. Fig. 4 is a vertical transverse sectional View taken through the front portion of the running gear on the plane indicated by the line 44 in Fig. 1. Fig. 5 is a longitudinal vertical sectional view taken on the plane indicated by the line 55 in Fig. 4.

Corresponding parts in the several figures are denoted by like characters of reference.

The box supporting frame of the wagon is composed of a pair of side bars 6-6 which are connected adjacent to their front ends by a cross bar 7, said side bars being also suitably connected intermediate their ends as by means of a cross bar 8. The side bars are provided with hangers 9 upon which the wagon box or body 10 is supported by means of pivots 11.

j j I Patented Oct. 11, 1910. Serial No. 522,228.

The rear axle 24 supports adjacent to each end thereof a body supporting spring 25.

The forward part of the running gear comprises the front axle 29 upon which the springs 30 are securely mounted by clips or fastening devices of well known construction. The front frame or bolster frame is composed of the front and rear bars 31 and 32 which are connected by the side bars 33; metallic braces, as 34 being employed wherever it shall be thought necessary in order to reinforce the construction. The bolster frame is supported upon the springs 30, the front ends of said springs being pivotally connected with clips 35 adjacent to the ends of the front bar 31, and the rear ends of said springs being slidably supported in keepers 36 adjacent to the ends of the rear cross bar 32. The bolster 37 is connected with the bolster frame by means of suitably arranged braces or hangers 38 and above the bolster is supported the reach bar 39, the front end of which is bifurcated to form the tongue engaging hounds 40. A brace bar 41 extends transversely across the reach bar, the ends of said brace bar being secured upon the side bars 33; and the fifth wheel 42 is securely mounted upon the brace bar 41 and upon the reach bar 39; spacing members 43 being interposed between the latter and the fifth wheel.

The king bolt 44 is composed of two hingedly connected members 45 and 46 the former of which is provided with a head 47 for the passage of the pivotally connected member 48. The lower member 45 of the king bolt extends through the brace bar 41, the reach bar 39 and the bolster where it is firmly secured with the head 47 resting upon the brace bar 41.

Firmly secured upon the underside of the cross bar 7 of the box supporting frame is a bracket 49 provided adjacent to its ends with suitable bearings wherein rollers 50 are supported for rotation; the axes of said rollers being in longitudinal alinement with each other and disposed longitudinally of the vehicle. It will also be observed that the pivotal connecting member 48 of the king bolt is disposed longitudinally of the vehicle and at right angles of the wheel carrying spindles of the front axle. The upper member 46 of the king bolt extends through suitable bearings in the bracket 49 and the cross bar 7 above which it may be provided with a nut or head which should not however be tightened to such an extent as to prevent the king bolt member 46 from having a limited longitudinal slidable movement or to interfere with the rocking movement of the king bolt member et6 in its bearings especially to permit the front truck to oscillate upon a turn. It will be' observed from the foregoing description that when the parts are assembled, the forward end of the box carrying frame will be supported upon the fifth wheel of the front running gear by the rollers Which When the axle is presented for straight movement in a forward direction are in alinement with each other and with the pivotal member 48 of the king bolt; hence, when the vehicle progresses over rough or uneven round, the entire front running gear is capable of tilting freely to one side or the other without disturbing the forward end of the box supporting frame and without communicating any violent movement to the latter, and at the same time without reducing the effective support of said box carrying frame upon the fifth wheel since the rollers 50 maintain their engagement with the fifth wheel in all positions of the front running ear. This freedom of movement exists not only while the front axle is in parallel relation to the rear axle, but when the front axle is being turned, although perhaps in a slightly less degree which may however be compensated for by permitting the upper member of the king bolt to have a very slight longitudinal movement in its bearings.

From the foregoing description taken in connection with the drawings hereto annexed the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. The construction of the improved dumping wagon is simple, inexpensive and thoroughly efficient for the purposes for which it is provided.

Having thus described the invention, what is claimed is 1. In a running gear for dumping wagons, a box carrying frame including a pair of side bars and a cross bar adjacent to the front ends of the side bars, a longitudinal bracket upon the underside of the cross bar, rollers supported for rotation upon longitudinal axes adjacent to the ends of the bracket, and a front gear including a bolster frame, a roller supporting fifth wheel upon said bolster frame, and a king bolt including a lower member secured in the bolster frame and an upper member hingedly connected with the lower member and having a bearing in the front cross bar of the box supporting frame.

2. In a device of the character described, a front running gear including an axle, springs supported thereon, a bolster frame supported upon the springs and having keepers for slidable engagement with the rear ends of said springs, and a fifth wheel supported upon the bolster frame; in combination with a box supporting frame including a pair of side bars and a front cross bar, a longitudinal bracket secured upon the front cross bar and having fifth wheel engaging rollers, and a flexible king bolt mounted in the bolster frame and having a bearing in the front cross bar of the box supporting frame, the pivotal member of said king boltbeing at right angles to the wheel carrying spindles of the axle.

In testimony whereof I afilx my signature in presence of two witnesses.

LORENZO H. YOUNG.
